House mouse and <br /> meadow vole captures were equal in number of 3 percent of total individuals trapped, and the single <br /> prairie vole accounted for 0.05 percent of the total small mammals trapped. <br /> During the four nights of trapping, 136 of a total of 720 traps were found closed but empty(18% <br /> unavailable). On two occasions, a single trap was found open and broken.The large number of closed <br /> traps found indicates the presence of other predatory mammals in the area. Several raccoon prints were <br /> observed on site. Raccoons can contribute to the predation of the oats left in traps and will tamper with <br /> traps while removing both the cotton stuffing and oat bait. <br /> 6 <br /> ERO Resources Corporation <br />
